[libvirt-users] Installation of libvirt on Ubuntu

Dear Ramaekers,

Perhaps I didn’t describe the problem clearly.

Libvirt has built-in driver for linux container, so, on Fedora, libvirt can be used to start and stop the linux container. (libvirt’s official website is libvirt.org). On Ubuntu, a user tool from https://linuxcontainers.org" is usually used to manage Ubuntu container. I noted that the use of the two user space tools are different. The problem is  I can realize sharing memory between containers on Fedora which is very important for me. But I wonder if I use the tool from https://linuxcontainers.org to manage Ubuntu container, whether I also can share memory between Ubuntu containers?

Libvirt is in the standard repositories… Why don’t you just install it with ex tasksel?

Onderwerp: [libvirt-users] Installation of libvirt on Ubuntu

Dear all,

I wonder if libvirt can work on Ubuntu.

As you know, it is very convenient to install libvirt on Fedora. I can download the libvirt packet from libvirt.org and install it using command ./configure, make and make install.

As I am going to install an open source simulation system named openairinterface, Ubuntu is the recommended OS, and I want to install the simulation system in libvirt lxc. (as you may know, there is another lxc user space tool on Ubuntu whose official website is "https://linuxcontainers.org", which I don't want to use).

My questions are:
1)  Can I install libvirt on Ubuntu with the same installation steps as on Fedora (i.e., manually download the tar.gz packet and install it locally)? I found a link talking about installation libvirt on Ubuntu which installs something like "libvirt-bin" (https://help.ubuntu.com/lts/serverguide/libvirt.html). I am not sure if libvirt can be installed following this instruction?

2)  How can I create the rootfs for a Ubuntu container if libvirt can be installed on Ubuntu? I create the rootfs for Fedora container using:
# yum --installroot=/root/fedora16linux container --releasever=19 install -y openssh, bridge-utils".
How can I achieve this on Ubuntu?

3)  If libvirt can work on Ubuntu, Can a disk file on the host OS be exposed to a Ubuntu container just like on Fedora?

With my warmest regards,

Cheng Wang
